Title: Gysin maps, duality, and Schubert classes
Abstract: We establish a Gysin formula for Kempf-Laksov flag
bundles and prove a duality formula for Grassmann bundles.
We then combine them to study Schubert bundles, their
push-forwards and fundamental classes.
This is a joint work with Lionel Darondeau.

Title: An application of microlocal analysis to control theory.
Abstract: In the first part of my talk, some preliminaries on microlocal
analysis will be discussed. In the second part of the talk, some
techniques to study the controllability of a system using microlocal
analysis will be explained. As an example of this approach, the lack of
null controllability of viscoelastic flows will be discussed.
